Today, I have seen that, the site command might be a little bit buggy for you and of course me currently and may be solve out for about a couple of week.

In brief, few SEOs and webmaster started observing that conducting a site command in Google for bigger sites would only call back 30 results. My friend also tweeted the problem on Twitter and he just mentioned the core problem while searching site command and then I also tried that command over Google and yes, he was right and I also taken the screen shot on that. Kindly check it out below.
